我收到一個ModuleNotFoundError錯誤，如下所示：
sample % python3 sample1.py
Traceback (most recent call last):
File "sample1.py", line 4, in <module>
from util_lib.helper1 import helper1_print
ModuleNotFoundError: No module named 'util_lib'
sample %
.../Testing/sample/:
sample1.py (calls helper1.helper1_print())
.../Testing/util_lib/:
helper1.py (has helper1_print())
代碼
樣品1.py：
import sys
sys.path.insert(0, '/Absolute/Path/Testing/util_lib')
from util_lib.helper1 import helper1_print
helper1_print()
**util_lab/helper1.py:**
def helper1_print():
print("Helper 1 Print")
我錯過了什么嗎？
當我使用相對路徑而不是絕對路徑時，我仍然有錯誤，見下文：
樣本1.py
import sys
sys.path.insert(0, '../Testing')
from util_lib.helper1 import helper1_print
helper1_print()
錯誤：
sample % python sample1.py
Traceback (most recent call last):
File "sample1.py", line 4, in <module>
from util_lib.helper1 import helper1_print
ModuleNotFoundError: No module named 'util_lib'

uj5u.com熱心網友回復：
正如我所見，您在插入path時似乎存在問題，并且目錄是not的子目錄sys.pathsampleutil_libTestingAPI_Testing
所以而不是
sys.path.insert(0, '/Users/pluu/PycharmProjects/API_Testing/util_lib')
嘗試
sys.path.append("abs/path/to/Testing")
